What it does

External Model Selection is an agent skill from Microck/ordinary-claude-skills. Choose optimal external AI models for code analysis, bug investigation, and architectural decisions. Use when consulting multiple LLMs via claudish, comparing model perspectives, or investigating complex Go/LSP/transpiler issues. Provides empirically validated model rankings (91/100 for MiniMax M2, 83/100 for Grok Code Fast) and proven consultation strategies based on real-world testing.

Its SKILL.md is about 4.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Development, covering Model routing and gateways. It works with MiniMax and OpenAI. The repository describes itself as: An unappealing collection of Claude Skills and resources.

When your agent uses it

  • Consulting multiple LLMs via claudish
  • Comparing model perspectives
  • Investigating complex Go/LSP/transpiler issues

Example prompts

  • “/external-model-selection”

Requirements

  • Python 3

Workflow steps

9 steps, taken from the step headings in SKILL.md.

  1. ALWAYS Use 10-Minute Timeout
  2. Launch Models in Parallel (Single Message)
  3. Agent Return Format (Keep Brief!)
  4. File-Based Communication
  5. Create Session
  6. Write Investigation Prompt
  7. Choose Strategy
  8. Launch Agents in Parallel
  9. Consolidate

What it can do on your machine

Read from SKILL.md and the folder at commit 1056d29. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash, python and markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

External Model Selection loads about 4.4k tokens when it runs. Until then it costs about 104 tokens; SKILL.md has 1,536 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~4.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,536 words (~4,361 tokens).

“Purpose: Select the best external AI models for your specific task based on empirical performance data from production bug investigations.”
